Lantern Softboxes are used by still photographers, filmmakers and videographers, for illuminating entire rooms with soft, even light. Choose a Chimera Lantern Softbox according to the size of the room, and your working light fixture.
This lantern softbox comes with a black skirt, which acts as a gobo, and provides more directional control of the light output from your fixture.
